SPECIFICATION forming part of Letters Patent NO. 69 5,627, dated. March 18, 19 02.

Application filed January 15, 1902.

To all whom it may concern:

Be it known that I, HERMAN ROSENBERG, a citizen of the United States, and a resident of the borough of Manhattan, in the city and State 'of New York, have invented a new and useful Imitation Leather and Process of Producing It, of which the following is a specification. I

My invention relates to imitation leather and the process of producing it, with the end in view of providing a serviceable article resembling leather, which shall have advantages over leather for many uses and which may be supplied at a cost materially less than the cost of genuine leather.

With this end in view my invention consists in coating a textile fabric-cotton drills, for example-with rubber, then vulcanizing the rubber-coated fabric, then applying to the rubber-coated surface a liquid mixture composed of vegetable oil, sulfur, turpentine,benzene,and a coloring substance, and finally vulcanizing this coating on the vulcanizedrubber coating. 7

My invention further consists in an imitation leather consisting of a textile fabric having an inner coating of rubber vulcanized thereon and an outer coating composed of oil, sulfur, turpentine, benzene, and a coloring substance vulcanized thereon.

In practice a piece of textile fabric-such, for example, as cotton drillsis coated with a rubber solutionsuch, for example, as is commonly used for making so-called rubber cloth and this coating of rubber is vulcanized on the fabric. The outer coating is then prepared by thoroughly mixing a vegetable oil, sulfur, turpentine, benzene, and a coloring substance in the following relative proportions: fifteen gallons vegetable oillinseed-oil, for examplethirteen pounds sulfur, fifteen gallons turpen'tine, fifteen gallons benzene, and forty-five pounds coloring sub- Serial No. 89,852.

stauce burnt umber, for example. The coloring substance may be ground in the mix- 5 ture of oil, sulfur, turpentine, and benzene and may be varied in quantity to produce diiferent shades. The proportions of the other substances composing the mixture may also be varied to produce a heavier or lighter 5o coating to suit the purposes for which the imitation leather is to be used. This outer coating after being applied to the vulcanized rubber coating is vulcanized, and the product is then complete.

If so desired, the rubber coating may be pebbled, as it is called, before it is Vulcan ized, and this appearance will be retained after the final coating is vulcanized.

The imitation leather thus produced is wa; 6c

terproof, will withstand heat and cold with-v out any tendency to crack or deteriorate, and

may be folded and worked into various shapes without any danger of breaking the coating.

' What I claim is- 1. The process of producing imitation leather consisting in coating a textile fabric with rubber, vulcanizing the rubber'coating on the fabric, applying a liquid coat composed of vegetable oil, sulfur, turpentine,ben- 7o HERMAN ROSENBERG.
